Technical Field
[0001] This utility model relates to the field of coal mine conveyor belt technology, and in particular to a buffer device for an underground coal mine electromechanical conveyor belt. Background Technology
[0002] In the process of coal mining, coal is often transported by conveyors. The most common type of conveyor is the belt conveyor. The main structure of the belt conveyor includes the transmission belt, the drive roller that drives the transmission belt, and the support roller that supports the transmission belt. The drive roller and the support roller that supports the transmission belt are installed on the conveyor belt frame.
[0003] However, when existing coal mine electromechanical conveyor belts lack a buffer function, coal and other materials falling from a height directly impact the belt, causing the belt surface to be subjected to greater friction and impact forces. This leads to rapid wear of the belt's covering rubber layer and reduces the belt's service life. Utility Model Content

[0029] Working principle: When the device is needed, turning on the first motor 2 will drive the first connecting rod 4 to rotate. The rotation of the first connecting rod 4 will drive the roller 5 to rotate, which in turn will drive the conveyor belt 14 to rotate. When coal mines apply significant pressure to the conveyor belt 14, the conveyor belt 14 will press down on the outer wall of the conveyor roller 11 and slide against it. When the conveyor roller 11 is pressed down by the conveyor belt 14, it will press down on the bearing roller 10, which will slide down against the outer wall of the inclined column 9. When the bearing roller 10 slides down, it will press down on the buffer roller 12.

When the conveyor belt 14 needs cleaning after use, turning on the second motor 16 will drive the second connecting rod 17 to rotate. The rotation of the second connecting rod 17 will drive the first bevel gear 18 to... When the first bevel gear 18 rotates, it drives the second bevel gear 19 to rotate. When the second bevel gear 19 rotates, it drives the threaded column 20 to rotate. When the threaded column 20 rotates, it drives the lifting plate 21 and the scraper 22 to rise and fall. When the scraper 22 rises to the lower surface of the conveyor belt 14, the conveyor belt 14 is opened. This allows the slag on the outer wall of the conveyor belt 14 to be scraped off as it slides, thus achieving the effect of cleaning the slag on the outer wall of the conveyor belt 14. Therefore, when using this device, it can not only buffer the pressure on the conveyor belt 14, but also buffer the impact and gravity pressure on the conveyor belt 14, reduce the wear of materials on the belt, extend the service life of the belt, and reduce noise, thus improving the working environment. It can also remove the attachments on the conveyor belt 14, ensuring that the material is evenly distributed on the conveyor belt 14, thereby achieving a stable conveying speed and flow rate. In this way, it can avoid the impact on the production progress caused by uneven material accumulation or slippage.
